214 CLASSIFICATION OF ANIMALS. 



of lizards, one of frogs, one of viviparous quadrupeds, and 

 one of oviparous quadrupeds, but they are not described as 

 gene, in the same way as, for instance, the Ketode. The 

 chief reason for this appears to be that he was influenced 

 by the popular grouping of animals, and preferred to describe 

 separately many animals, such as, for example, monkeys, 

 bears, and chamseleons, which the common people had not 

 included in groups known by popular names.* 



In addition to the groups referred to above as being the 

 ones best-defined by Aristotle, there are a few others which 

 may be included in his classification, because he describes 

 them sufficiently clearly to enable them to be identified 

 with orders or families of modern classifications. The 

 groups referred to are included, therefore, in the subjoined 

 tabular representation of Aristotle s classification. The 

 numbers following the various groups represent approxi 

 mately the numbers of different kinds of animals referred 

 to by Aristotle :
